Opal the Sun Dragon Working Draft.
When they're all the domains, it's literally ALL OF THEM, not a selection.
It's perfectly legal to have a dragon be able to cast cleric list spells as arcane spells and NOT give it domains, so it might have been deliberate.
Or we just forgot.
I'd give him druid spells too. He is Lord of the Neutral Dragons after all, and what's more neutral in D&D than a Druid?
Putting together the above would make:
Spells: Opal is a 20th-level sorcerer and a 20th-level cleric. He can cast cleric spells and spells from cleric domains as arcane spells and can also cast druid spells as arcane spells or cleric spells. Opal has access to
all the domains available to the neutral dragons he rules (For the amber, jacinth, jade, moonstone, Mystaran jade, Mystaran onyx, and pearl dragons, these are Animal, Charm, Darkness, Healing, Knowledge, Luck, Plant, Trickery, Water and Weather). In his natural form, Opal can cast his spells with but a word.
Let's see:
Amber Dragon—No Domains, but can cast druid spells as arcane spells.
Jacinth Dragon—No Domains?
Jade Dragon—Plant and Trickery
Moonstone Dragon—Healing and Knowledge
Mystaran Jade Dragon—Charm, Knowledge, and Plant
Mystaran Onyx Dragon—Animal, Darkness, and Water
Pearl Dragon—Luck and Weather
I'll fill in the Domain Lists later:
1st level—Animal, Charm, Darkness, Healing, Knowledge, Luck, Plant, Trickery, Water, Weather.
2nd level—Animal, Charm, Darkness, Healing, Knowledge, Luck, Plant, Trickery, Water, Weather.
3rd level—Animal, Charm, Darkness, Healing, Knowledge, Luck, Plant, Trickery, Water, Weather.
